Selecting a MoJo Model

A MoJo is not one thing it is a custom system that is built to suit the end user, as the nature of limited mobility is very individual it needs careful consideration as to what the best configuration of a MoJo will be.
  
You must consider
1) how much ability the end user has
2) and what is to be controlled.  ie Games- PC/Consoles or Mouse or Other assistive aids using relay outputs

A MoJo in its simplest form can be used as a very high sensitivity switch that operates another assistive aid and at the other end of the spectrum could a fully featured games console joystick.  

MoJos' are built with even number of channels up to a a max of 16 ie MoJo16.    

If the MoJo is to be used as a simple but very sensitive switch then a the MoJo Basic model will suffice and probably be quite a small system perhaps only a two or four input ie a MoJo2 or MoJo4.

Important: 
Modern console controllers allow fully able bodied users to operate very many controls using every digit of their hands.  It is unlikely a  very compromised user will come close to this and certainly not with the same dexterity therefore the user must be aware their ability to operate every possible control will be compromised.  The degree of compromise is down in part to the users ability and the size and complexity of the MoJo system purchased.  Remember the more sensors used the more complex the set-up will tend to be for a users carer.   The Advanced MoJo allows multiple buttons to be operated by a single input but the more buttons allocated to a individual input then the slower the access speed will become.   For buttons requiring fast & frequent operation then one button per input is recommended.   

A Breath inputs is available on any MoJo and can be a useful addition if finger motion  is extremely compromised.   Breath control uses the last channel and has a prefix P for pressure.  So a MoJo2-P will still have two channels but the last one is dedicated to being the breath input.


For the less able the user may only be able to push a very slight distance with no option to push AND pull as is used with a conventional joystick motion and is required by a MoJo zJoy(stick).

Under these circumstances a combination of three zSticks can be used to control one joystick,
three channels are required to support this. Therefore the minimum would be a MoJo 4 leaving only one channel left for button control.  This is unlikely to be satisfactory therefore MoJo6 would be the minimum recommended for a practical joystick.

If the user has sufficient movement to operates a zJoy sensor which is used like a conventional push/pull joystick then this occupies only two channels of a MoJo so a MoJo4 would have two inputs left available for other probably buttons controls but is still something of a compromise.

Other Options 

Relays:  Every channel of a MoJo can have an associated relay output to operate other assistive aids in the same ways a push button or a switch would.

Analogue outputs:  Each pair of channels can support a pair of analogue outputs that are variable resistors.  These are isolated from other pairs but not from each other.
